Caffeine vs Millstream
Both from Behr's palette. Caffeine reads as greige-grey, while Millstream reads as blue — two distinct hue families, not close cousins. Millstream (LRV 61) reflects noticeably more light than Caffeine (LRV 20), a difference of 41 points that becomes especially apparent in rooms with limited natural light. Caffeine runs red while Millstream is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 38.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Caffeine vs Millstream in Real Spaces
2 real rooms side by side. Seeing Caffeine and Millstream in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Millstream will make the room feel meaningfully brighter than Caffeine would.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Millstream reflects noticeably more light off the walls, making the space read more open than Caffeine.

5 simulated room previews — drag the slider on each to see Caffeine on one side and Millstream on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
